shared/photos content

I am not much of a playbook user, but I find myself porting a game for it and integrating scoreloop. I would like the user to be able to choose a scoreloop profile picture from within the game.

I see that I with the user_shared permission I can access photos in 'shared/photos', but I do not know how a typical user ends up with photos in that folder. Is there someone else I can find potential profile pictures for them, or is that the only place?

Re: shared/photos content

Usually, whenever users take photos using the Camera applications or download pictures from somewhere, they end up in the "shared/photos" directory. The "shared" directory is pretty much the only directory hierarchy that the applications can share (for ensuring application sandbox). Hence, other applications can save pictures in those directories and that is how those directories get filled with pictures, music and videos etc (I believe that is the only place where they can save the media files).
